9. As microbes growing on SDA will also be counted as part of TYMC, why usually are not the growth promotion tests necessary to be done on SDA Along with the bacterial strains?
– Inokulasikan pada media bets baru dan media bets sebelumnya yang telah lulus uji GPT (dilakukan secara duplo)
Following a specified incubation period of time, observe the plates for growth and count the colonies attained in Each individual plate and record the effects in Annexure-II.
Previous to the availability of higher-high-quality reference resources, growth promotion testing was commonly done by plating a serial diluted microorganism suspension on each a whole new and a Earlier released media batch to check recoveries. This method proved challenging in getting precise success
Begitu juga sebalikanya apabila dari media yang ditanam bakteri yang jumlahnya misalkan seventy five cfu dan ternyata jumlah bakteri yang tumbuh lebih dari fifty% dari jumlah bakteri yang ditanam dapat disimpulkan bahwa pengujian jumlah bakteri dan jamur pada sampel produk sudah legitimate.
